I've unlocked and rooted my galaxy Nexus and everything worked great I tried cyanogenmod but ended up sticking with 4.0.1 that was a couple months ago. Recently I started getting the update message from sprint so I found the google images and made the mistake of downloading and flashing the 4.2.2 GSM/HSPA+ instead of the the 4.1.1 CDMA/LTE version the install worked but the network was gone and when I tried to flash the backup I find out that my external is corrupted. I went back and downloaded the proper "toroplus" 4.1.1 version and flashed everything fine but the network is still gone I called up sprint and tried to activate the phone but the tech couldnt get the edit option from the SPC_Checker It seems like the radios that came with the google version are missing some options. I'm starting to get frustrated so I thought I would reach out for some help.
Android 4.1.1 (toroplus) CDMA/LTE
